Purpose – The purpose of this paper is to shed light on some important limitations of the ISO 26000 standard for corporate social responsibility (CSR) for the credible communication of corporate CSR claims. The paper aims to identify and explore firm-level strategies to signal adherence to the standard effectively and their legitimacy consequences for the standard. Design/methodology/approach – The identification of firm-level signaling strategies is mainly derived from an institutional description of the ISO 26000 standard and based on anecdotal evidence from current business practice, initiatives that have been taken worldwide by organizations such as national standards institutes, the ISO 26000 text and adjacent ISO documents, including ISO post-publication surveys. The paper is grounded in signaling theory. Findings – Five signaling strategies for firms are derived and explored which may reduce information asymmetries and engage in efficacious signaling of their underlying CSR quality and thus guide the communication of firms’ adherence to the ISO 26000 standard. Research limitations/implications – The findings urge to empirically investigate the use of ISO 26000 signaling strategies including their legitimacy consequences for firms. Practical implications – The findings of this paper have implications for decisions firms make when considering working with ISO 26000 and communicating their adherence, notably regarding the enhancement of the credibility of their CSR claims. Also, it offers suggestions for certification organizations, national standards bodies and policy makers that want to encourage the adoption of CSR standards, ISO 26000 in particular. Social implications – This paper may have implications for evaluating the CSR claims of firms by stakeholders and broader society. Originality/value – This paper is the first one to address inherent signaling problems of ISO 26000 and to identify signaling strategies to counter these problems in a structured way.

02-05-2016An operational amplifier based instrumentation amplifier (IA) with a common-mode rejection ratio (CMRR) independent of resistance tolerances is presented in this paper. The CMRR is determined by the operational amplifier characteristics. The IA shows a high CMRR up to 100 kHz. Moreover, since the presented IA operates in the current domain, no large internal voltage swings occur, making it an interesting choice for low-voltage applications in situations where common-mode disturbances may affect the signal processing.
Semantic unification during sentence comprehension has been associated with amplitude change of the N400 in event-related potential (ERP) studies, and activation in the left inferior frontal gyrus (IFG) in functional magnetic resonance imaging (fMRI) studies. However, the specificity of this activation to semantic unification remains unknown. To more closely examine the brain processes involved in semantic unification, we employed simultaneous EEG-fMRI to time-lock the semantic unification related N400 change, and integrated trial-by-trial variation in both N400 and BOLD change beyond the condition-level BOLD change difference measured in traditional fMRI analyses. Participants read sentences in which semantic unification load was parametrically manipulated by varying cloze probability. Separately, ERP and fMRI results replicated previous findings, in that semantic unification load parametrically modulated the amplitude of N400 and cortical activation. Integrated EEG-fMRI analyses revealed a different pattern in which functional activity in the left IFG and bilateral supramarginal gyrus (SMG) was associated with N400 amplitude, with the left IFG activation and bilateral SMG activation being selective to the condition-level and trial-level of semantic unification load, respectively. By employing the EEG-fMRI integrated analyses, this study among the first sheds light on how to integrate trial-level variation in language comprehension.

31-12-2018In het project werken onderzoekers van het Lectoraat samen met publieke organisaties toe naar een tool waarmee onderstromen in het publieke debat rondom issues eerder kunnen worden opgemerkt. We exploreren met welk algoritme we patronen in geruchtvorming en mobilisatie kunnen opsporen, en tevens hoe we de interactie tussen newsroom-analisten en de output van een monitoring tool het beste kunnen vormgeven.Doel Het doel van dit project is een brede en structureel toepasbare aanpak van het issuemanagement: Hoe kunnen de communicatieprofessionals van publieke organisaties potentiële issues op sociale media vroegtijdig opmerken? Resultaten We willen dit bereiken door enerzijds kennis en inzicht te vergaren en anderzijds de uitkomsten daarvan voor publieke organisaties te vertalen in praktische handgrepen: tools, handleiding, training. Looptijd 01 oktober 2022 - 30 september 2024 Aanpak Via cases ingebracht door de praktijkpartners en focusgroepen staan we in nauw contact met het consortium. In de eerste werkpakketten onderzoeken we de verschillende cases aan de hand van discoursanalyse. De inzichten die we hierbij opdoen, gebruiken we vervolgens om te bekijken hoe we de interactie tussen mens en machine het beste kunnen vormgeven en wel zo dat er ten behoeve van de communicatie en het management van issues via interactieve visualisaties steeds weer triggers afgegeven worden. Op basis van de opgedane inzichten richten we een interface in. Deze maakt het analisten en communicatieprofessionals mogelijk om vroegtijdig issues te signaleren.
Carboxylated cellulose is an important product on the market, and one of the most well-known examples is carboxymethylcellulose (CMC). However, CMC is prepared by modification of cellulose with the extremely hazardous compound monochloracetic acid. In this project, we want to make a carboxylated cellulose that is a functional equivalent for CMC using a greener process with renewable raw materials derived from levulinic acid. Processes to achieve cellulose with a low and a high carboxylation degree will be designed.
Size measurement plays an essential role for micro-/nanoparticle characterization and property evaluation. Due to high costs, complex operation or resolution limit, conventional characterization techniques cannot satisfy the growing demand of routine size measurements in various industry sectors and research departments, e.g., pharmaceuticals, nanomaterials and food industry etc. Together with start-up SeeNano and other partners, we will develop a portable compact device to measure particle size based on particle-impact electrochemical sensing technology. The main task in this project is to extend the measurement range for particles with diameters ranging from 20 nm to 20 um and to validate this technology with realistic samples from various application areas. In this project a new electrode chip will be designed and fabricated. It will result in a workable prototype including new UMEs (ultra-micro electrode), showing that particle sizing can be achieved on a compact portable device with full measuring range. Following experimental testing with calibrated particles, a reliable calibration model will be built up for full range measurement. In a further step, samples from partners or potential customers will be tested on the device to evaluate the application feasibility. The results will be validated by high-resolution and mainstream sizing techniques such as scanning electron microscopy (SEM), dynamic light scattering (DLS) and Coulter counter.
